From 250 miles above our home planet, this time-lapse imagery takes us over the Pacific Ocean’s moon glint and above the night lights of San Francisco, CA. The thin hue of our atmosphere is visible surrounding our planet with a majestic white layer of clouds sporadically seen underneath. The International Space Station is currently home to 6 people who are living and working in microgravity. As it orbits our planet at 17,500 miles per hour, the crew onboard is conducting important research that benefits life here on Earth. Credit: NASA
This edge-on view of a galaxy located about 45 million light-years away, showcases its beautiful arms, which swirl like a whirlpool around its bright central region.

Astronomers took this image as they were observing an extraordinary exploding star – a supernova – near the galaxy’s central yellow core! The star rapidly evolved from a supernova containing very little hydrogen to one that is hydrogen-rich — in just one year. This rarely observed metamorphosis was luminous at high energies and provides unique insight into the poorly understood final phases of massive stars. By studying similar galaxies we hold a scientific mirror up to our own, allowing us to build a better understanding of our galactic environment, which we cannot always observe, and of galactic behavior and evolution as a whole.
